The invention relates to a reinforcing element (1) comprising a first (2) and a second reinforcing mat (3) having metal mat rods (6), which are welded at angles to each other at junction points (7), which reinforcing mats (2, 3) are held spaced apart from each other at a normal distance (9) by rod-shaped spacers (8) with respect to the first mat plane (4) and the second mat plane (5) of the reinforcing mats. The spacers are metal (8) and are permanently connected to individual mat rods (6) of the first (2) and second reinforcing mat (3) by welding connections (10), preferably resistance welding connections, wherein at least individual spacers (8) protrude outward at least beyond the first mat plane (4) of the first reinforcing mat (2) in a direction (11) pointing away from the second reinforcing mat (3) by a first protrusion length. The invention further relates to a double wall furnished with the reinforcing element and a method for producing the reinforcing element and the double wall.

A thermally broken truss (10) for a cage of a structural building panel, comprising: first and second elongate outer support members (12, 14); first and second elongate intermediate support members (16, 18) interposed between the first and second outer support members (12, 14); at least one first connecting member (20) interconnecting the first outer support member (12) and the first intermediate support member (16); at least one second connecting member (22) interconnecting the second outer support member (14) and the second intermediate support member (18); and a thermally insulative fastener (24) which fastens the first and second intermediate support members (16, 18) together in spaced apart relationship, thereby providing a thermal break between the first and second outer support members (12, 4). A thermally broken structural building panel (40) is also provided.
